Why Oxygen Purity Monitoring Matters 

Maintaining correct oxygen purity is essential for patient safety and device compliance: 

• Prevents under- or over-oxygenation 

• Supports compliance with relevant standards such as (ISO 80601-2-69 , ISO 13485) 

• Enables continuous quality monitoring 

Oxygen sensors for concentrators provide real-time feedback, ensuring devices maintain a consistent oxygen concentration, which is critical for both therapeutic and clinical applications. 

How Sensors Ensure Correct Oxygen Output 

Sensore medical oxygen sensors detect oxygen levels with high precision, allowing oxygen concentrators to automatically adjust oxygen flow: 

• High sensitivity: Accurate readings between 20.9% and 96% O2 

• Rapid response: Detects changes instantly for dynamic adjustment 

These sensors are ideal for both PSA oxygen concentrators and membrane-based systems. 

Integration with Concentrator Electronics 

Sensore oxygen sensors are designed for easy integration with device electronics: 

• Low power consumption for portable and home care devices 

• Compact size to fit tight housings 

• Simple analog and digital interfaces 

This seamless integration helps OEMs design reliable, compliant oxygen concentrators. 

Reliability Considerations 

Medical devices demand sensors that maintain performance over time: 

• Minimal measurement drift over the device lifecycle 

• Tested under real-world operating conditions 

Sensore sensors deliver long-term reliability for critical oxygen monitoring applications. 

Sensor Lifetime 

Designed for seamless integration into medical devices, Sensore sensors support both analog and digital interfaces and can be easily integrated into existing control architectures. Their compact design and low power consumption make them especially suitable for portable and home care oxygen concentrators. Optimised sensor design and materials help reduce maintenance requirements while ensuring consistent oxygen purity monitoring throughout the concentrator’s service interval.
